Yes it is possible.
I bought a single form one to do my grid of M12's from here: http://www.drill-service.co.uk/Produ...20000&Tool=799
You would use the 6mm one with a max cutting OD of 4.8 so you can get into the 5mm pilot holes.
If you want to go quicker, you can get the multipitch endmills that can make the thread in a single pass but they do become more expensive.
Have a look on NYCCNC's videos for how to set it all up in Fusion 360.
Machine tools and 3D printing supplies. Expanding constantly.
Ouch! thats a bit spendy for a thread :)
Just found a Torch video and they have a similar head to my Tapmatic - theirs is Procunier but the action is the same it seems.
The only benefit they have is that its all pre-programmed canned cycle stuff. I don't have that luxury but at least it proves it can work.
I will have a look at the specs on the head for tap-travel below the stop point and see if i can come up with a method of programming :) From memory it was 5mm below the stop point to where the feed disengaged so for a 10mm deep thread you would stop feeding at 5mm, wait for the clutch to disengage then feed out.
Hmm, thought i could get smart and do it in Fusion360 which comes up with this code...
(T1 D=6. CR=0. - ZMIN=-10. - RIGHT HAND TAP)
G90 G94 G91.1 G40 G49 G17
G28 G91 Z0.
G0 X-5. Y0.
G43 Z15. H1
G98 G84 X-5. Y0. Z-10. R4. F1000.
G28 G91 Z0.
This should be a M6 thread 10mm deep with a 4 second pause, But it seems Mach3 does not recognise G84 so thats out, whatever G84 really is :)
G84 is rigid tap cycle.
You should have bought one of these.
£450 landed in UK.
No computer, no monitor, no windows license, no Mach licence, No CSIO box of tricks.
Does rigid tapping, tool changer, pendant, all built in.
These are going to be a game changer in the future.

Ouch, nice box. Didn't know about it then though, I also like the more graphical nature of Mach3, tweaks, tricks, customisations etc :)
This might be getting there, treat it as a drill, chip-break operation, full retract, set peck depth to thread depth minus the 5mm for tapping clutch, pause before retract to allow clutch to disengage then retract.
I se for a 6mm x 1mm thread so i chose 500 rpm and 500mm/min feed should match the pitch rate of 1mm/rev ??
Only issue i see here is that it rapids out as G0, will look at that.
(1)(T10 D=6.1 CR=0. TAPER=118DEG - ZMIN=-5. - DRILL) G90 G94 G91.1 G40 G49 G17 G21 G28 G91 Z0. G90 (DRILL2) M5 M9 T10 M6 S500 M3 G54 M7 G0 X0. Y0. G43 Z16. H10 Z2. G1 Z-5. F500. G4 P4. G0 Z6. Z16. M9 G28 G91 Z0. M30
Sorted, the guys on the Fusion360 forum edited a post-processor so it can feed in, dwell and then feed out.
Should have it sorted nicely :)
